Google Gemini CLI

A simple command line interface for interacting with Google Gemini (Previously Bard), written in Rust.

This CLI allows you to save chat history as a Markdown file at a specified absolute or relative path in realtime

and handles graceful exit with Ctrl+C.

Prerequisites

You need to have Rust and Cargo installed on your system. If you don't have them, you can install them from the official Rust website.

Installation

Install from cargo. Add -f at the end to force update. (cargo install bard-rs -f)

cargo install bard-rs

or

1. Clone the repository to your local machine:

   git clone https://github.com/Alfex4936/Bard-rs
   

2. Change the working directory:

   cd Bard-rs
   

3. Build the project:

   cargo build --release
   

The executable binary file will be located in the target/release folder.

Usage

Before using the Google Gemini CLI, you need to obtain your session cookie. To get the session cookie, follow these steps:

1. Go to Google Gemini in Chrome.
2. Open Chrome Developer Tools (F12 or Ctrl + Shift + I).
3. Go to the "Application" tab.
4. Under "Storage" > "Cookies", click on "https://gemini.google.com".
5. Find the cookies with the name __Secure-1PSID (Must) and __Secure-1PSIDTS (Optional), and copy the values.

Now you can use the Google Gemini CLI:

Supported options: -s (__Secure-1PSID cookie), -t (__Secure-1PSIDTS cookie), -m (if present, it'll print other Gemini's responses for your prompt), -p (if present with path, it'll save your chat history as markdown.), -e (if present with .env file location, it'll use that session cookie)

It'll save as your first prompt message. (eg: "Hey yo" -> gemini_hey_yo.md)

bard-rs --psid <your_psid> --psidts <your_psidts> --path ./

bard-rs --psid <your_psid> --path ./

Replace <your_psid> and <your_psidts> with the value you copied from the Developer Tools.

If you don't want to save the chat history as a Markdown file, skip --path:

bard-rs -p <your_psid>

If you don't want to pass that long session in terminal, use .env file (refer to .env_sample)

bard-rs -e .env -p ./

If you prefer not to specify a path, bard-rs will automatically search for the .env file in the following locations: the argument-provided path, the current working directory, and the directory of the bard-rs binary.

(GEMINI_HISTORY is required in .env if you want to save the chat history as markdown file everytime.)

bard-rs

above command is same as bard-rs -e .env

.env file must contain PSID key. (it is derived from __Secure-1PSID)

![IMPORTANT] Need __Secure-1PSID and __Secure-1PSIDTS

! using echo PSID=... > .env might cause encoding problem that dotenv cannot read and end up causing no session key error.

PSID=~.

Resolving "SNlM0e not found" Error

[!IMPORTANT] if you are getting "SNlM0e not found. Check your cookies." even with __Secure-1PSIDTS

1. Clear your cookies. (In Chrome, DevTools - Application - Cookies)
2. Login again.
3. Obtain new __Secure-1PSID (Seems like typically contains a numerical identifier representing the logged-in user.)
